Description

Male (Fig. 1 a ). Wingspan 23-25 mm. Antennae filiform, brown; head dark brown; thorax, tegulae and legs brownish-yellow; abdomen dorsally brown. Fore-wing ground colour brownish-yellow with dark brown posterior line from near apex to middle of inner margin, near the discal cell with two large dark puncta; cilia whitish-yellow, terminally black. Hind-wing ground colour brownish-yellow, median line indistinct at costa.

Male genitalia (Fig. 3 a ). Uncus bifid apically, with two shorter processes; two lateral processes apically curved inwards. Subscaphium hairy. Gnathos strip-type with serried tooth. The valvae weak membranous straps; median valval process weak. Sacculus process short sclerotised, enlarged apically. Aedeagus short and broad with a cluster of cornuti.

Female: unknown.

Diagnosis

This new species resembles S. irresecta obscura Whalley, 1976 , but the ground colour of wings is yellow (reddish-brown in the latter, Fig. 1 a , b ), the oblique line from apex to middle of dorsum is straight, dark brown (ochre in the latter). In male genitalia, the uncus is broader, the sacculus process is shorter than S. irresecta obscura , the aedeagus is broader basal (Fig. 3 a , b ).

Etymology

The species is dedicated to Mr. Paul Ernest Sutton Whalley, in honour of his marvellous work on Thyrididae .

Distribution

China: Yunnan (Chuxiong), Guangdong (Shaoguan).

Notes

Our study shows that S. irresecta obscura seems more closely related to the new species than to S. irresecta irresecta morphologically and zoogeographically. Judging from the holotype pictures (Fig. 2) from the Natural History Museum (2014), the hind-wing pattern of S. irresecta is also showing the same characteristics.
